This was brilliantly easy, and I happened to have everything on hand, which is how I roll when it comes to cooking. I thought it would come out dull, but it was just delicious. And, of course, it's good for baby, too. You could very easily leave the chicken out for a vegetarian option.
2 cups of cubed, roasted winter squash, roughly pureed (I used butternut)
2 cups of cooked white rice (I'm sure brown would be just as nice; I happened to use Jasmine)
Shredded cooked chicken--1 or 2 cups?
1 cup plain, low-fat yogurt
1/2 tsp. nutmeg
Mix all together. Grease a lidded quart casserole and fill it with the mixture. Grate some nice sharp cheddar cheese (or whatever you have) on top. Cover with a thick layer of bread crumbs. Drizzle a little olive oil on top. Pop in preheated 350 oven. Bake for about thirty minutes, or until bubbling and looking good enough to eat.
